Using a Systems-Focused Simulation to Rapidly Prepare for Large Volume COVID-19 Vaccination.

SUMMARY STATEMENT: The goal of vaccinating large numbers of staff and nonstaff against COVID-19 with a novel vaccine necessitated rapid modifications to an existing workforce vaccination program. We performed a series of 3 iterative systems-focused simulations and debriefings in the span of 1 week to evaluate existing vaccination clinic space, trial a new physical space for the COVID-19 vaccine clinic, identify existing process gaps, and determine necessary changes for maximum efficiency and safety. By using iterative systems-focused simulations, we were able to perform a gap analysis on the existing program, develop and stabilize new processes, and focus on emergency preparedness.
